Recipe Preparation

Preheat oven to 350°. Toss breadcrumbs with oil and dried oregano on a rimmed baking sheet and season with salt. Toast, tossing halfway through for even browning, until golden brown, 8–10 minutes. Let cool.

While the bread is toasting, blend anchovies, egg yolk, shallot, garlic, Parmesan, vinegar, lemon juice, mustard, Worcestershire sauce, and hot sauce in a blender until smooth. With motor running, gradually stream in both oils; blend until smooth and emulsified. Season dressing with salt and pepper.

Toss puntarelle, boquerones (if using), and 2 Tbsp. dressing in a large bowl (reserve remaining dressing for another use); season with salt.
